BMW 3: Climate Control
As in previous BMW hybrid vehicles, an electrically powered air conditioning
compressor is used in
the G20 PHEV. Because the A/C compressor has an electric motor, it is possible
to operate the air
conditioning independently of the combustion engine. Thus the customer can enjoy
the cooling effect
of the air conditioning even while driving in pure electric mode and while
stopped.
The high-voltage battery unit is cooled by the vehicle's refrigerant's circuit.
The stationary climate control is also available in the G20 PHEV.
